FIELD: medicine. SUBSTANCE: method involves separating the newborn from placenta by transecting umbilical cord 25-30 cm far from umbilical ring. Length of umbilical cord residue attached to afterbirth is equal to 26-28 cm. The afterbirth is examined and pulped immediately after birth to find pathological areas and indurations. The afterbirth is weighed as a whole without being prepared to calculate placental fetal coefficient from formula K= (A-B)/C, where K is the placental fetal coefficient, A is the afterbirth mass including tunics and umbilical cord residue, B is the extraplacental tunics and umbilical cord residue mass equal to 103 g, C is the fetus mass at birth. Coefficient K = 0.13-0.19 when children being born during 38-40 weeks long gestation period, and K=0.2-0.23 in the cases of premature birth at 32-37 weeks time, the placentas are considered to be compensated without macroscopically determinable pathological changes in them. The gestation period being greater or less, chronic secondary placental insufficiency (developing within II and III pregnancy trimester) is of great importance from the point of view of high risk of pathology occurring in neonatal and newborn period. EFFECT: high diagnostic resources and informative capacity. 1 tbl
